Whole file verification data；
B2. current upgrading terminals is calculated the whole file verification number of whole program upgrade file by described whole file verification algorithm
According to, and judge whether to be consistent with the whole file verification data received；If being consistent, go to B3；If not corresponding, main website record is current
Upgrading terminals whole file verification exception also goes to the 4th step；
B3. action is restarted in current upgrading terminals execution reset, and is transferred to from temporary storage area by program upgrade file
Formal application area, is then calculated the whole file verification number of whole program upgrade file by described whole file verification algorithm
According to, and judge whether to be consistent with the whole file verification data received；If being consistent, the current upgrading terminals of main website record upgrades successfully,
Go to the 4th step；If not corresponding, main website record current upgrading terminals file transfer exception also goes to the 4th step.
4th step, current upgrading terminals upgrading processing terminate；Main station judging the most all acquisition terminals upgrading processing terminates,
If otherwise selecting next acquisition terminal to be current upgrading terminals and go to second step, if then remote upgrade terminates.
Main website subsequent processing steps: inquiry upgrading terminals inventory in each acquisition terminal program version, and with this secondary program liter
The version contrast of level file, it is that upgrade status is abnormal that version contrasts inconsistent acquisition terminal state recording, is contrasted by version
Consistent acquisition terminal communication channel switches to information gathering channel.
Wherein, in second step, the single frames checking algorithm detailed process for each frame blocks of files is as follows:
S1. initialize: making variable W_CRC is 16 bits, and each bit value is zero；Make data pointer i=1；
S2. take 8, the left side of variable W_CRC and preserve to variable W_CRC1；Take 8, the right of variable W_CRC and preserve
To variable W_CRC2；
S3. read the i-th byte data of present frame blocks of files, and these data carried out XOR with variable W_CRC2,
Income value is N；
S4. with variable W_CRC1, the numerical value of the n-th sequence in cipher table being carried out XOR, income value preserves to variable
W_CRC；Cipher table is made up of the hexadecimal values predetermined order of at least 256 >=0x0 and≤0xffff；Rising of cipher table
Beginning sequence number is zero；
S5. data pointer i=i+1 is made, it is judged that it is complete whether present frame blocks of files reads, if then going to S6, if otherwise turning
To S2；
S6. the numerical value of variable W_CRC is negated, obtain the single frames verification data of present frame blocks of files.
For ease of understanding single frames checking algorithm, lift an application example:
Certain frame blocks of files contains two byte datas, and the 1st byte data is 10110011, and the 2nd byte data is 01011010.Left
Moving is logical shift left, moves to right as logic shift right.
Cipher table is as shown in the table, and containing 256 hexadecimal values, order also represents with hexadecimal values:
